Smith numbers Backgroundwhile skimming his phone directory in 1982, Albert Wilansky, a mathematician of Lehigh University, noticed that the telephone number of his brother-in-law H. smith had the following peculiar property: the sum of the digits of that number was equal to the sum of the digits of the prime factors of that number. got it? Smith's telephone number was 493-7775. This number can be written as

Smith-waterman algorithm is a dynamic programming algorithm proposed by Smith and Waterman in 1981 to find and compare local similarity regions, and many later algorithms are developed on the basis of this algorithm. This is a two-sequence local comparison algorithm, the two unknown sequence is arranged, through the letter matching, delete and insert operation, so that two series reached the same length, in

Http://www.36kr.com/p/5277.html Smith was initially an agent and an artificial intelligence program in the Matrix. His mission was to eliminate messy programs and humans and maintain system order. Otherwise, the simulation of the real world would be turbulent. Smith was more open, smarter, more adaptable, and more lethal than other agents from the very beginning. In Matrix 1,

For a positive integer n, if its sum equals the sum of all of its factorization, then that number is called the Smith number. For example, the sum of 31257=3*3*23*151,31257 's figures is 3+1+2+5+7=18, and the sum of all its factorization figures is 3+3+2+3+1+5+1=18, so 31257 is a Smith number. Write a program to determine if the positive integer input is a smith

To analyze a matching network using Smith round charts ① the matching network into several segments, each corresponding to an impedance graph or a point on the admittance map; ② according to the operating frequency, the resistance (resistor) or reactance (capacitor and inductor) of the series element, the conductivity of the shunt element (resistor) or the electrical Na (capacitor and inductor), wherein the reactance of the inductor equals the pos
